Grade 11 physics: SPH3U1-01 | Physics Lab Report | Specific Heat Capacity of Brass | | Jin Jin Shi | 2012/12/6 | Instructor: Mr. Nailer | I. Introduction The amount of heat required to raise the temperature of a solid body depends on its change in temperature (ΔT)‚ its mass (m)‚ and an intrinsic characteristic of the material forming the body called specific heat (cp). The heat is calculated from the equation II. Purpose The purpose of this laboratory is to determine

was higher than the actual melting point of pure aspirin; 135°C. The phenol test showed that the product is not a pure aspirin by expressing purple color. TLC results weren’t high enough to conclude that the product was a pure aspirin. Overall‚ the lab wasn’t successful due to the low percentage of aspirin that were produced. Out of 2.0 grams of aspirin‚ only 0.7862 grams of pure aspirin were produced. So the percent yield was only 39%. Errors could be made during filtration process and the melting

The effect of aqueous extracts of four medicinal plant extracts on citrinin production from both fungi has been reported in Table 5 and Table 6. All the four plant extracts effectively decreased citrinin production ranging from 14.2 to 91.8% in P. notatum and 13.4 to 90.3% in A. niger. Amongst all the four extracts RhazyastrictaDecne was more efficient than all in inhibiting the citrinin production ranging from 22.4 to 91.8% in P. notatum and 32.6 to 93.2% in A. niger (Table 5 and 6)

things‚ that if the force of the egg doesn’t have something to fall into‚ like cotton or balloons‚ then it will break‚ because the force needs to be shared or it takes over the egg. With that‚ I understood a basis of how the device should be. This lab is designed to be very innovative with making devices so that nature can be defied. An egg that is supposed to break on contact from seven meters up will be safe and won’t break. The egg drop showcases endless laws of physics‚ and it also encourages

Introduction: Mitosis occurs in all eukaryotic cell tissues and produces genetically identical daughter cells with a complete set of chromosomes. In humans‚ mitosis produces somatic cells that are diploid‚ which means they contain two non-identical copies of each of the twenty-three chromosomes. One copy is derived from the person’s mother and the other from the person’s father. Meiosis‚ on the other hand‚ occurs only in testis and ovary tissues‚ producing sperm and ova (eggs). The gametes that

go through the whole process of osmosis. Also‚ a lot of the experiment was rushed as we were under pressure to finish as quickly as possible. Unfortunately the time constraint was caused by and outside influence unrelated to the lab itself‚ and so next time we could do a lab under normal conditions where there are no outside disturbances. There were weight differences in the potatoes which could have caused thicker potatoes to absorb more than others. It was a little impossible to obtain the same

Bacterial Morphology Demonica Britt Microbiology DL1 March 23‚ 2013 Abstract This lab was performed to identify and familiarize with a microscope while precisely observing various bacterial shapes and their arrangements in different types of specimens of bacteria. The microscope parts and capabilities were clearly identified and used successfully and the bacteria were clearly illustrated showing the bacterial shapes and arrangements with all the appropriate magnification being utilized.

The two natural sources used in this experiment were an orange (the peel contains limonene‚ which is a terpene) and a dichloromethane solution of clove oil (which contains eugenol‚ an acetogenin). To isolate the eugenol

I) Introduction In this lab‚ a test was conducted to determine how the relative redox activity of chloroplasts from spinach leaves‚ which were performing photosynthesis‚ would change when in the presence or absence of light. To observe these changes in redox activity‚ the chloroplasts were exposed to DCPIP‚ a chemical that changes color according to such activity. By determining the redox activity of the chloroplasts‚ it could then be inferred which chloroplasts were photosynthesizing more actively
